NONV'IBRATORY VENTILATOR CLOSURE.

Application led March 19, 1925, Serial o. 16,814.

To aZZ lwhom 'it may concern.'

Be it known that I, Mir/ron FRANKLE, a citizen of the United States, residing at Des Moines, in the countv of Polk and State of Iowa, have invented certain new and useful lmprovements in a Nonvibratory Ventilater Closure, of which the following is a specification.

This invention relates to an improved ventilator for the cowls or hoods of automobiles generally, and particularly for the Ford type of automobiles, and has for its principal objects to provide such a construction that, upon closure of the lid, air will be efectively prevented from moving through the ventilator, and that vibration occasioned by the lid will be prevented.

With the foregoing objects in' view the invention presents a novel and useful construction, combination and arrangement of parts as described herein and claimed, and as illustrated in the accompanying drawing, it being understood thatchanges in form, size, proportion and minor details may be made, as found to be of advantage, said changes being determined by the yscope of the invention as claimed.

ln the drawing, Fig. 1 shows a side view of the front part of an automobile provided with a ventilator. Fig. 2 is a plan view of an elastic, endless ring or band. Fig. 3 is a plan view, partly in section, of a ventilator constructed in accordance with the invention. Fig. a is a transverse section through the ventilator on line 4 4 of Fig. 3, also showing the ventilator attached to the hood or cowl, thev lid being closed. Fig. 5 is a similar sectional view of parts to that shown in Fig. 4, the lid being swung to open position.

Referring now particularly to the drawing, the invention is shown and described in connection with the cowl or yhood 6 of an automobile, said cowl being provided with an aperture 7 communicating with the interior of the vehicle. rlhe ventilator consists of an endless, upright, grooved collar 8 provided with an endless flange 9 of approximately rectangular form in plan, said flange being adapted to be disposed outwardly of the margin of the aperture 7 and to be secured to the cowl or hood forwardly of the vehicle body 10.

At 11 is indicated a lid mounted to permit swinging movements, as indicated at 12, frena the rear part of the dange 9, said lid being provided with parallel wings 13 which project inwardly of the hood to control the direction of movement of'air entering the ventilator from the atmosphere. y

Numeral 14 indicates a handlek or pulland-push-bar for the use of an operator who, while occupying the drivers seat, may manually raise the id to the position shown in Fig. 1 or Fig. 5, or may cause' the lid to swing downwardly to the position shown in Figs. 3 or 4.

ln order that vibration will be prevented which otherwise might be caused by the intermittent engagement of the lid with its metallic support, and that a complete closure may be made of the ventilator, l provide an endless, elastic ring or band, circular in cross-section, adapted to be disposedin the I groove m of the collar.

By referring to Figs. 4 and 5 of the drawing it will be seen that the outer side of the collar is concaved. The band or ring 15 should be elastic, and preferably is constructed of hollow india-rubber tubing. and is of such proportion that it will fill and that a material and consider/'able proportion thereof will project outwardly of the groove pe, said outwardly projecting part of thel ring being an important feature in operation; and when the lid is lowered to a closed position the lip or endless flange 16 of the lid will engage the ring to prevent any movement of air through the ventilator and to prevent vibration which otherwise would be occasioned by intermittent unequal or incompleteengagement of said lip-or flange 16 with the collar. The band or ring 15 normally is of somewhat less circumference than the grooved 'collar and must be stretchedand elongated somewhat to mount it on the collar, after which its tension tends to lhold it in place. without the aid of any securing means.

ln the construction of ventilators for the cowls of motor vehicles, the mounting of the lid is suiflciently loose to permit it to be readily elevated or lowered manually whenever required, and therefore the metallic parts, when the lid is lowered, are subject .to vibration unless an elastic filler is provided; but by use of the elastic ring, 'as described, all noise occasioned by vibration will be eliminated. Also in cold weather it is desirable that no air shall enter the automobile through the ventilator. and since the ring projects outwardly of the collar it will entering. The ring when so mounted andv engaged by the flange of the lid also prevents rattling by lateral as well as.up and down movemen e I claim as my invention,-

. 1., In a ventilator closure, the com-bina-l tion with the cowl at the front part of an automobile, said cowl being provided with an aperture, and a collar havingan upright, laterally grooved wall and mountedon the cowl outwardly of the margin of sjaid aperture, of an elastic ringremovably mounted in said roove and held therein by its inlid having a downwardly projecting, endless Hangeand adapted to be swung` downwardly 80 to dispose its Hange outwardly of said groove in to close engagement with the 'outer y circumferential side `of said elasticring, to prevent admission of air and the rattling of the closure b -either 'lateral or vertical movement of t e Harigev against the collar.

2. In a ventilator closure, the combination with an apertured cowl and anupright col- *lar provided with an endless groove on itsm lter lateral face and having a Harige, 4said `ffbcollbeing adapted to be disposed above f if 'a the l.nge with .saidlan e secured to that part' of thev cowl-outwar ly of the margin'T of said aperture, of an endless, elastic ring normally circular in cross-section and of less gjaalmulus thanI the ltop margin of said collar and adapted to be removably disposed within the groove and held therein by tension `and to project outwardly of the collar, anda lid having a downwardlyirojecting,endless Hange and adapted to be moved downwardly to dispose itslHange-.into closefengagement .vertical movement of the Hange against the collar.

3. In a ventilator closure, in combination,

a cowl having an aperture, an Vupright collar provided with an endless lateral groove and having an endless flange adapted to be secured to the cowl outwardlyof the margin herent e'asticity, and a hingeably mounted of said aperture, a lid having a 4downwardly projecting, endless Hang'e and adapted to be moved downwardly `to dispose its endless Harige outwardly of the' endless groove of the collar, anda-hollow endless, HeXible ring normally circular in cross section and adapted to be removably disposed with a" part engaging and held by tension within said groove and with a part projecting out- 4wardly a material and considerable distance from said endless groove for closely engaging the endless Hange of said lid to .prevent admission'- of air and the rattling of'sthe A`-closure by either lateral or vertical movement of the- Hange against the collar..

In testimony whereof, I have affixedmy signature.
